Should I Take Part in a Cancer Prevention Clinical Trial?

People decide to be part of a cancer prevention clinical trial for many reasons. For example:

  • Some people who have a higher cancer risk join a cancer prevention trial because they want to take a more active role in their health care. Also, because study participants get regular and careful medical attention, some health problems may be found early.
  • Some people feel good about helping medical knowledge advance. If the study agent turns out to work against cancer, it may help others. For example, prevention trials showed that aspirin helps prevent heart attacks, and now many people take aspirin daily on their doctor's advice.

Even when they don't lead to new therapies, clinical trials often answer important questions and help move research forward.

You need to weigh the benefits and risks for yourself. The list in the next section may help you do that. You also may find it useful to talk with family members or friends, your health care providers, and anyone you know who has been in a clinical trial.

Remember: You are the only person who can make this decision, and if you join a clinical trial, you can change your mind at any time  even after the study starts.
